Paris, France 🇫🇷 / Canada 🇨🇦 (Montréal)
Systems programmer specializing in high-performance applications and full-stack development. 
About Me
I'm a passionate developer with dual French-Canadian nationality, focusing on building high-performance systems and full-stack applications. My expertise spans from low-level systems programming in Rust to modern web development with TypeScript and Python.
I'm particularly interested in performance optimization, concurrent systems, and creating tools that solve real-world problems. Whether it's building a painting application with SIMD optimizations or integrating AI models into desktop apps, I thrive on technical challenges that push the boundaries of what's possible.
Why Work With Me?
Performance
Always looking to write faster, more optimized code.
Reliability
Follows testing and writing standards for maintainable code.
Up to date
Keeps up with industry standards and best practices. Always looking to learn new technologies.
Featured Projects
Rusty Painter
High-Performance 2D Painting Application
Problem
Desktop painting tools struggle with large canvases due to memory constraints and performance bottlenecks.
Solution
Built a lightweight painting app using Rust that supports massive canvases (8000x8000+) through lazy-loaded tiled storage and GPU texture atlases, maintaining 60fps interaction.
Technical Highlights
- â–¸Tiled canvas architecture with lazy loading for memory efficiency
- â–¸SIMD-optimized color compositing (4x speedup)
- â–¸Multithreaded brush engine with pressure sensitivity
- â–¸Robust undo/redo system across layers and transforms
- â–¸Non-destructive selection and transformation tools
âš¡ 8000x8000 canvas @ 60fps
Transcript-UI
OpenAI Whisper Desktop Transcription Tool
Problem
OpenAI's Whisper model lacks an accessible GUI for desktop audio/video transcription workflows.
Solution
Created a GTK4 desktop application that integrates Whisper with ffmpeg for seamless audio/video transcription and live capture functionality.
Technical Highlights
- â–¸Integrated ffmpeg pipeline for audio/video processing
- â–¸Async audio streaming for 30+ concurrent sessions
- â–¸Live capture mode for real-time transcription
- â–¸Cross-platform desktop UI with GTK4
âš¡ Real-time transcription with live capture
Todo System
HR Competence & Task Management Platform
Problem
HR teams need integrated tools for both competence tracking and task management without juggling multiple systems.
Solution
Developed a full-stack web application combining competence matrices with task boards, enabling HR teams to manage skills and workloads in one place.
Technical Highlights
- â–¸Task board interface with drag-and-drop
- â–¸Competence matrix for skill tracking
- â–¸User role management and permissions
- â–¸RESTful API backend with PostgreSQL
âš¡ Full-stack HR management solution
